The type of scam that’s the most successful in duping the Android user is an old-fashioned fake virus alert. According to the report, fraudulent advertisements account for over 50 percent of all malware detections from the Dfndr Security app. That’s an increase of over 50 percent over the previous quarter.

PSafe CEO Marco DeMello told Tech.co that deceptive affiliate marketers use these fraudulent techniques to get their clients more conversions. PSafe finds that “the actual advertiser is often unaware that the partners they’ve hired to help them with growth marketing are leveraging these scammy techniques to boost numbers.”

Although scams surrounding adult dating sites dropped by about 13 percent as compared to the previous quarter, dating scams still make up about 19 percent of the total malware detections so far this year.

In these scams, users are redirected to phony adult dating sites that earn a click-through commission, or they are asked to allow notifications from a site that then encourages them to download malware.

Finally, the fake giveaways category made up about seven percent of overall malware scams on Android this year. In these scams, users are told they’ve won something of value, and are encouraged to download a malicious app, click through a bad link, or subscribe to a texting service that charges their service provider in order to receive the prize.

What’s the best way to avoid these scams? Common sense will get you most of the way there, but when in doubt a terrific security app – like those listed here – is essential.
